Claims.

This invention relates to bobbin drives for winding machines.

Various drives for winding bobbins have heretofore been proposed but these have different objectionable features. For example, it has been proposed to drive the bobbin by a friction roll or wheel which engages the yarn wound on the bobbin, and with the bobbin carried on a pivotal mounting which is moved out of contact with the friction roll upon breaking of the yarn being wound or upon filling of the bobbin. The yarn package thus produced, while reasonably satisfactory, is capable of improvement and, for some kinds of winding, the shifting of the bobbin is undesirable.

It has also been proposed to wind bobbins on fixedly mounted centers but the drive for the bobbins has not been wholly satisfactory, partic-- ularly because the bobbin cannot be held free from rotation at the commencement of the winding, or the resumption of the winding after an interruption, or when the bobbin is filled. No satisfactor separate and individual bobbin drive, independent of the drive for other bobbins in the machine, has heretofore been available in Winding machines operating with fixedcenters.

It is the principal object of the. present invention to provide an improved bobbin drive for Winding machines which will overcome the obiec tions heretofore encountered with prior bobbin winders.

It is a further'object of the present inventionto provide. a bobbin drive, Working'on fixedly mounted centers, in which the bobbin drive may be connected and disconnected as desired, while the bobbin is supported on its axis.

It is a further object of the present invention to provide an improved bobbin drive which may be connected and disconnected as desired, without swinging the axis of the bobbin, and in which the bobbin may remain at rest when disconnected. from its drive.

It is a further object of the present invention to provide an improved bobbin drive which includes mounting elements on which the bobbin is supported for rotation, a driving member which is normally continuously operated, and an axially movable controlling member interposed therebetween.

It is a further object of the present invention to provide an improved bobbin drive which includes, with the driving mechanism, suitable control mechanism for disconnecting the driving mechanism under certain conditions.

Other objects and advantageous features of the invention will be apparent from the specification and claims.

The nature and characteristic features of the invention will be more readily understood from the following description, taken in connection with the accompanying drawings forming part hereof, in which:

Figure l is av front. elevational view of a bobbin drive in accordance with the. present invention, parts being broken away to show the details of construction; and

Figure 2' is an end elevational view, as seen from. the left.

It should, of course, be understood that the description and. drawings herein are illustrative merely, and that various modifications and changes may be made in the structure disclosed without departing from the spirit of the invention.

Like numerals refer to like parts throughout the several views.

Referring now more particularly to the draw"- ings, a horizontal rail it is shown, as a fragmentary portion of the frame of a winding machine, together with a traverse bar H, having mounted thereon and movable therewith a yarn or strandv guide eye -2, and a drive shaft 5-3 extending parallel to the rail Hi, the traverse bar H and shaft l3 being actuated in any desired manner common to Winding machines.

At a plurality of predetermined locations on the. rail H), dependent upon the size and capacity of the winding machine, and for each bobbin B to be wound, a housing i4 is provided rigidly secured. to the rail in.

At a location spaced from the housing id, dependent upon the length of the bobbin is, a bobbin end support i5 is provided which includes a bracket [6, secured to the rail is. The bracket is has an upwardly extending arm I-i, pivotally mounted thereon by a pivot pinis. A spring, re, carried by the bracket is: and in engagement with the arm iii, normally resiliently urges the upper portion of the arm It towards the lei-t (see rig. 1), while permitting movement to the right Ior insertion and removal of the bobbin B, as here'- inaiter explained.

The arm H, at its upper end portions, has theouter race 21:: of a ball bearing: 21 nxedly mounted therein. The inner race 22 0-1" the bearing 2 i has a bobbin" supporting spindle 23 carried therein. The bobbin engaging end of' the spindle 23 is adapted to engage the end of the bobbin B in any desired manner in supporting relation, and for this purpose, and to increase the usefulness and adaptability thereof, it is preferred to employ a stub end 24 extending into the central opening in the bobbin end and a plate 25 having a beveled rim 26 engaging in a beveled groove 21 in the end of the bobbin B.

The housing l4, partially encloses a driving gear 28, keyed or otherwise secured to the shaft 13 for rotation. therewith. The gear 28 is in mesh with a driven pinion 29 mounted on and secured to a clutch ring 39 for rotation therewith, the ring 39 being mounted on and secured to the outer race 3! of a ball bearing 32. The inner race 33 of the ball bearing 32 is secured to a supporting sleeve 34 which is fixedly mounted in the housing 14. It will thus be'seen that the clutch ring 39 is supported on the sleeve 34 by the bearing 32 and can be continuously rotated.

Extending through the sleeve 34 a clutch shaft- 35 is provided, axially movable a limited distance, having a clutch plate 36 on the inner end thereof. The clutch plate 36 has, on the inner face thereof, a beveled rim 31 for engagement in a a beveled groove 21 in the end of the bobbin B and a stub end 38 extending into the central opening in the bobbin end.

The provision of grooves 21, in both ends of the bobbin, permits the insertion of the bobbin B without the necessity for selecting the driven end.

The clutch plate 36 has, on the outer face thereof, a beveled rim 39 for engagement for driving in a beveled groove 49 in the clutch ring On the outer end of the clutch shaft 35,1an operating disc 41 is provided having an outer beveled end face 42.

The housing I4 has pivotally mounted thereon, by a pivot pin 45, a latch lever 46. The latch lever 46 has a locking shoulder 41 thereon, and at the upper end may be provided with a handle 48 for manual drive releasing actuation.

The housing l4 also has mounted thereon, by a pivot pin 49, a latch control lever 59; the lever 59 has a downwardly extending arm 51, which preferably has one end of a connected thereto, the other end of the spring 52 being connected to the lever 46 below the pivot pin 45.

The lever 59 also has an upwardly extending arm 53 with a handle 54 for manual actuation of the lever 59 for resetting or effecting drive engagement.

The lever 59 has a central locking and drive controlling arm 55 with a hooked portion 56 at the free end thereof for engagement with the edge of the lever 46 at the shoulder 41. The arm 55, between its ends, is movable within a bracket 51, which is carried on the housing 14. The arm 55 in its downward and locked position is out of engagement with the operating disc, and in its upper position, as limited by the bracket 51, is adapted to engage the disc 4| and move the tension spring 52 l clutch shaft 35 inwardly to disengage the rim 39 from driving contact with the clutch ring 39.

The latch lever 46, in addition to its manual actuating handle 49, may be actuated in any desired manner to release the lever arm 55 from engagement at the shoulder 41, permit its upward movement and disengage the rim 39, from contact with the clutch ring 39. One suitable actuating mechanism is shown and includes a shaft 69, pivotally mounted in the housing l4, with a finger 6| for engagement with a tapered end 62 on the lever 46. The shaft 69 also hasan arm 4 63 mounted thereon, at a location between the ends of the bobbin B. The arm 62 has at its outer end an eccentrically mounted roller 94 carried by a roller pin 65. The roller 64 is adapted to be actuated, as hereinafter pointed out, when the bobbin B has been filled to the desired extent.

The mode of use of the bobbin drive in accordance with the invention will now be pointed out.

The drive shaft 13 is rotated and the traverse bar H is continuously reciprocated in any desired manner. The rotation of the shaft !3 is effective, through the gear 28 and the pinion 29, for continuously rotating the clutch ring 39, which as previously indicated is supported by the bearing 32 on the fixed sleeve 34.

Before the insertion of a bobbin B, the lever 59 will be in its upper position with the arm 55 out of engagement at the shoulder 41. The arm 55, in this upper position, will be in engagement with the operating disc 49, and the clutch shaft 35 will be moved and held axially so that the rim 39 will be out of engagement with the clutch ring 39.

A bobbin B, having end grooves 21, has one end moved into contact with the stub end 24, and

that end. The bobbin B will now be supported, may be rotated manually if desired, but is not driven.

When it is desired to drive the bobbin B, the

handle 54 is moved forwardly so that the arm 55 of the lever 59 is engaged at the shoulder 41.

The downward movement of the lever 59, through the spring 52, tends to position the lever 49 for such engagement. The downward movement of the arm 55 moves it out of engagement with the operating disc 4[ so that the shaft 35, by reason of the force of the spring [9, acting on the arm I! is effective, through the bobbin B and the clutch plate 36 for moving the rim 39 into engagement with the clutch ring 39. The bobbin B is then driven by the clutch ring 39 and the clutch plate 33 for winding, with yarn uided thereon by the guide eye l2. Upon the actuation of the latch lever 46, in any manner, to release the lever 59 and permit its upward movement, urged by the spring 52, the arm 55 engages the operating disc 4|, and moves the clutch shaft 35 and clutch plate 36 so that the rim 39 is out of engagement with the clutch ring 39.

The bobbin B will then come to rest or may be stopped manually, if desired.

When a predetermined quantity of yarn has been wound on the bobbin B, the outer face of the yarn comes into engagement with the peripheral face of the eccentric roller 64, causes it to rotate and by forcing the arm 63 away from the face of the bobbin B causes the shaft 69 to be moved. This movement of the shaft in turn moves the finger 6| against the lever end 62, and

the lever46 is moved to release the lever 59 and permit movement thereof to its upper position,

to the operator by the positions of the handles 3 73. 8am. V. V g V With. a plurality of bobbins operated with drives as herein described, the. stopping of one bobbin, for any cause, does not. interfere with the continued operation of other bobbins.
